This invention relates to wood slicing ma.- .chines andparticularly pertains to machines for producing battery separator plates.

It is the principal object of thejpresent invention to provide a generally improved machine of the character referred to which is of'simpleqand inexpensive construction, efficient in operationand having a greater ca- -pacity than prior maehinesof: the same nature. H U a i Incarryingout this object into practice I provide a. machine having a. movable table carrying a knife for shearing slices from a billettof wood; The table-is reciprocated bot-l1" longitudinally and transversely during eachstrokeso asto obtain. a shearing action ofthe knife .on the wood. At each end. of its stroke the table: is moved to operative position relative to thebillet of wood so that each stroke of the table will be productive.

One form which the invention may as sume is exemplified in the following description' and illustrated by way of example in the accompanying. drawings, in which:

Referringmore particulrwly; to the accompanying drawings, indicates a frame or base of a woodslicing machine which is particularly adapted. for the PBOLlUOtlQD 1 of a batter y separator plates. machine, 5 however, is capable ofusein slicing wood for various other purposes. i

Vertically arranged on the base 10 are four columns 11. Theupper ends-of theseycolumns are fitted with bearings 12 and at their lower ends they are formed with pads which I are securely bolted or otherwise secured to the base 1O. The columns 11 are arranged in pairs,the column of each pairbeing in transversealignment. The bearings of each pair of columns reciprocably support altransverse member 14. .j The arrangementof the columns is such that the transverseanembers are dis posed inparallelism one at each end of the base and transversely of the latter.

Each member 14 is formed with a central sectionvlfi, the opposite ends of which terminate in trunnions 16 which are reciprocably mounted inthe bearings12. Exteudingbe tween the transverse members is apair of guides .17 which are arranged in parallelism longitudinally of the machine and atninety degrees to the transverse member 14. The endsofthe guides 17 are securely fixed in the central portions of the transverse members 14. Thus, the guides 17 and the transverse members 14 are relatively rigidjaud in effect form a transversely reciprocable carriage.

Guided on the guides 17 for reciprocation longitudinally thereof is what I prefer to term atable 18. This table is formed with a bearing 19 at each corner which are slidably disposedion the guides 17 so that the table 18 may be reciprocated longitudinally of the guides.

In practice I may fix the guides 17 to the table 18 and have them slidably engage the transverse members 14. This, however, is a mere matter of design and comes within the scope of the appended claims.

The table 18 isformed with acentrally located longitudinal slot 18a at one side of which is arranged a knife 20. This knife eX- tends parallel to the slot and has a (:uttiug edge overlying the slot. The knife as illusofthe knife.

To support a block of wood I provide a block holder22 whichislixed to the frame and overliesthe table. This block holder is formed with a vertically arranged magazine 23 which is adapted to receive blocks ofwood to be sliced. The lower end of this magazine is open so that blocks of wood fed therein will. pass vertically theretlu'ough and rest upon the table 18 exposing the lower end thereof to the cutting action of the knife 20.

Thus as the knife engages the To reciprocate the table I provide a drive shaft 24 which may be driven by a pulley or by a directly connected motor as desired. This drive shaft 24 is fitted with a bevel gear 25 which is in mesh with abevel gear 25 keyed or otherwise secured on a Vertically arranged table drive shaft 27. At its upper end the shaft 27 is fittedwith a crank arm 28 carrying a crank pin 29. j A connecting rod 30 is connected atone end'tothe crank pin 29 and at the other end to the table .as indicated by the numeral '31." It is obviousthat'when the shaft 27 revolves that the'c'rank pin 29 will. revolve and through the medium of the connecting rod 30 impart reciprocation'to the table 18.; I

' Co'incidently with the reciprocation of the table 18 the carriage whichcarries the table 18 accomis 'rec'procated transversely. This is as follows: A cam 32 is supported by the frame and is driven fromthe drive shaft 24 at twice the speed of the shaft 27. Coop-. crating with the cam 32 is a cam arm 33 one end'of which is secured ona rock shaft 34 jonrnalled on the base 10 and extending longitudinally thereof. The cam arm 33 at its other end is fitted with a cam roller 35 engaging a canifgroove 36 in the cam '32. This! groove is so formed thatthe shaft 3 1 will be rockedat the proper'intervals. Secured at their lower ends to the shaft3 1are rocker arms 37 the upper ends of which are connected to the transverse members 14 as indicat ed in Fig. 3 of the drawings. lVhen the ma chine'isin operation the arms 37 oscillate transverselv of the machine at the proper intervals to move the carriage and the table carried thereby'transversely as the carriage is reeiprocated longitudinally.

In operation of the device assuming that the parts of the machine are inthe positions illustrated in-Fig. 1 of the drawings, it will be seen that the table 18 is at the extremity of its outer stroke and that the carriage is over to the end of its stroke in the direction of the arrow'B.

ture. While I 20 will pass through the block with a shearing action, shearing a slice of wood from the lower end of the block. This slice of wood as it issheared passes between the knife and the pressure bar 21 and discharges.

hen the table 18 is moved to the full extent of itsreturnstroke, the carriage will be at the end of its stroke in the direction of the arrow A in Fig. 1 and the knife will have passed completely through the block of wood 23. The formation of-the cam groove is'such that when this position is reached the carriage will be quickly moved transversely in the direction of the arrow B to return it to operative position for a successive operation and when the carriage commences moving'in the direction of the arrow D the carriage will be gradually moved in the direction of the arrow A, so that theknife will again pass through the block and slice it. When the carriage reaches the outer end of itsstroke in the direction of the arrow D, thecam again moves the carriage rapidly in th'e'direction. of the arrow B to place the knife in position for a successive cut and allow the'block in the magazine to lower and engage the pressure bar portion of the ble 18 is productive. This is of importance as it makes the machine one of large capacity.

-It is alsoapparent-that the construction of the machine is very'simple and that it will be comparatively inexpensive to manufachave shown thepreferred form of rious changes may be made in its construction by those skilled in the art without departing fromithe spirit of the invention as defined in the appended claimsflj Having thusdescribed my invention, what I claim and desire to secure by Letters Patentisr "1- 1.
